How Arizona assessment appeals generally work (state framework reviewed 2026-08-02 from official Arizona sources): County assessors determine full cash value and limited property value for locally assessed property and apply the statutory percentage for the property's legal class. Assessment ratios vary by class; class-three primary residential and class-four other residential property are generally assessed at 10%, while other classes use different percentages. A property owner may petition the County Assessor for review and then appeal the assessor's decision to the applicable County Board of Equalization or State Board of Equalization. Arizona law also permits a valuation or classification appeal directly to court within the applicable statutory period without exhausting the administrative route.
Arizona deadline framework: A real-property petition to the County Assessor is generally due within 60 days after the Notice of Valuation. An administrative appeal from an assessor decision is generally due within 25 days, with the proper board depending on county and statutory circumstances. A court appeal following an administrative decision is generally due within 60 days after mailing of the most recent decision; a direct court appeal has its own statutory calendar.
Local variation in Arizona: County assessors control local records, notices, review meetings, and submission methods. The next administrative forum differs by county and circumstance, and centrally valued property follows a separate Department route. Property class, mixed use, limited value, and the tax year materially affect the analysis.
Before relying on a date: Resolve the county, tax year, property class and use, locally or centrally valued status, Notice of Valuation mailing date, and any prior petition, then verify the current ADOR form, assessor receipt deadline and decision, correct equalization board, and the applicable direct or subsequent court deadline.
